WikiBooks is yet another excellent resource that was spawned by an amazing Wiki technology. The goal of the project is development of free and open textbooks. You’ll find few thousand textbooks arranged into several bookshelves, which are similar to categories. Both the interface and the textbooks are available in several languages.

Look and feel updated
I have done a bunch of updates and upgrades in the last few days. Most of these were internal and hidden from the eye though. So, in order to thank you for all that patience, I give you a slightly different view of this page.
As you can see, I have reoganized the long list of links that was on the right side of the page. It was split into two parts, each of which is much shorter. I have also improved a bit on the CSS, so now you can actually enjoy the site in browsers other than Firefox. There are still a few glitches here and there, but I am working on it.
Let me know what you think about this look via comments. Also, feel free to point out any problems (and solutions) that you have with this blog.
Fixing SpamAssassin high load
Since few days before the upgrade of the home server to Fedora Linux Core 3 I was seeing high load spikes from SpamAssassin. After the upgrade, my load average stayed at 10-15 almost the whole day. I was trying to fix it, but to no avail. At first, I have switched off the Bayes filtering, thinking that that is the part to be blamed. It didn’t help. Than I forced SpamAssassin to run in non-Unicode environment, thinking that that might improve things. Nope.
After playing some more with configuration and Googling, I decided to visit #spamassassin IRC channel. In a matter of seconds I was pointed to the this bug report. I will be trying the posted patches shortly. For now though, a simple change of number of maximum children helped a lot. I have reduced it to 2 from the default value of 5. (Edit /etc/sysconfig/spamassassin)
My home workplace
Olga and I started to prepare the room for the baby. As you might know, we don’t have a spare room just for that, so we have to get rid of our computer room. Today some of the first irreversable changes went in, but before that, I thought that it would be cool to keep a few pictures of the original setup. It will be fun to look at this in 5-10 years.
My table is gone now…
